21.5-hp (16-kW) engine

Engine oil and fuel filters

The S240 Tractor has a large 44.3-cu in. (726-cc) displacement engine with premium features that provide superior performance and reliability:

Large cleanout ports, integrated into the engine shroud, are located over the cylinder heads to allow for easy inspection and removal of any debris that may have collected there.
Premium engine oil and air filtering systems and cooling design provide increased reliability and engine life.

The 21.5-hp (16-kW) V-twin engine provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions:

V-twin cylinder design for greater torque, lower vibration, and improved sound quality
Electronic ignition for fast starts
Cast-iron cylinder liners for longer engine life
Overhead valves for excellent power and fuel economy
Full-pressure lubrication and oil filter for cleaner oil, prolonging engine life and extending the time between oil changes
- Also more effective when operating the tractor on an incline
In-line fuel filter for reliable operation

Engine speed lever and spring-loaded choke lever

Engine hood in open position

The engine speed lever and choke control lever are separate controls:

The engine speed lever is easy to use - there is no need to worry about pushing too far and engaging the choke as on single throttle/choke lever systems.
The choke lever is spring loaded so the operator cannot accidentally operate the tractor with the choke on.

Engine hood opens wide for easy access to service points:

It is easy to inspect and clean the engine area.
Important service points are exposed.
Cleanout ports designed into the engine shroud make cleaning the engine cooling fins easy.
The high-quality engine used in the S240 does not require an 8-hour oil and filter change because improvements in the manufacturing process and quality of parts, components, and oils have eliminated the need for the short interval oil change requirement.
